source itself. The device drivers are used to communicate with the hardware directly
and to pass the information between Zaptel and the hardware.

While Asterisk itself compiles on a variety of platforms, the Zaptel driv-
ers are Linux-specific—they are written to interface directly with the
Linux kernel. There is a project at http://www.solarisvoip.com that pro-
vides Zaptel support for Solaris. There is also a project that is working
to provide Zapata drivers for BSD, located at http://www.voip-info.org/
tiki-index.php?page=FreeBSD+zaptel.

First we will discuss the ztdummy driver, used on systems that require a timing interface
but that do not have hardware. Then we will look at compiling and installing the drivers.
(The configuration of Zaptel drivers will be discussed in the next chapter.)
